I know the phat one downgrades, but you should check the SKU Model link from the first post of this thread to find out if the slim does or not.

also have you checked the clip is actually sitting flush?
are there any components next to the NOR that is preventing the clip from "clicking" in place?
have a good close look

i have a slim ps3 with firmware 3.72 model CECH-2504B and i want to know if it possible to downgrade to firmware 5.55 to jailbreak
okay i have a question can i downgrade a sp3 cech004 from firmware 4.40 to 3.5 if yes can you let me know how to do it and what i need
Is this information still current?
I had my nicely hacked 3.55 PS3 until some idiot upgraded to 4.46ofw... Grrr... That's what I get for not keeping it spoofed to at least the current number...
I'm not afraid of hardware hacking it, but if someone was come up with a software solution, that would be preferable... Been away from the scene for a while, so I thought I'd see if there was anything new first.
Wow! Well this at first glimpse all seems very complicated but I'm beginning (as a complete novice) to understand what jailbreaking and downgrading entail.
My situation (and it seems there are thousands of different scenarios so its a wonder any ps3's can be jailbroken) is this.
My PS3 is one of the older ones...the Fat 60gb CECHCxx and at some point...probably last year, I upgraded the software, think I was bought uncharted3 or COD and it said I had to!
It upgraded to 4.11 according to my settings menu.
Other than that the console is standard out of the box... I have reflowed it once after it YLOD'd on me but she's working fine now.
With this info and it being an old machine.....can I jailbreak it using software, or does the fact I upgraded it to 4.11 mean I need to open it up and solder some new chips or whatever in? Find it hard to believe that upgrading it like that is completely irreversible!
Anyway, a very informative forum you have here and I'm pleased to have found it
CECH "C" = NAND... What only leaves you with One of Two Options.

Sadly both Options will require you to solder up 50 individual Points on your PS3. There is NO Softmod past OFW3.55! And, the E3 NOR Flasher is only for use on NOR Chipped PS3s (i.e. Anything after CECH "H")...
